The WBI Conditioning Program is built from the same principles employed in the hitting and throwing programs – increase proficiency of athletic ability while developing functional strength, versatility and flexibility.  Simply put, this program seeks to develop and enhance an athlete’s overall motor coordination through movement stimulus with various types of exercises and routines.  We believe an athlete must experience and master a variety of motor skills to ensure future athletic success and injury prevention.   

This is not a weight lifting* or an endurance program geared towards a specific sport but rather it is a broad-based strength training and movement stimulus development program set to achieve superior athletic ability and conditioning.
